POCKET-ALARM.

Sp cification of Letters Patent-N0. 26,001, dated November 1, 1859.

T0 all whom *Zt may concern:

Be it known that I, ISAAO GOODSPEED, of Norwich, New London county, Connecticut, have inventecl a new ancl useful Pocket, Thief, ancl Burglar Alarm, ancl that the following clescription, with the accompanj ing drawings, form a full, clear, and exact speoification thereof.

My invention consists in the procluction ancl manufature of my pooket alar1n, which consists of a shell o1 case of such form ancl size, as to loe conveniontly oarried aloout tl1e person wit-h suitable mechanism inclosecl therein for causing the explosion of a per cussion cap upon the removal of any article to which the alarm is attaohed.

The accompanying clrawings representmy maohine.

Sin1ilai letters represent si1nilar part-s in all the views.

Figu1e l, is an exterior sicle elevation of the machine. Fig. 2 is a eclge view of ditto. Fig. 3 is a sicle view with oute1 casing next the observer removecl, to exhiloit the interior mechanism.

a, represents the external case.

b, represents the hammer.

0, represents the cap tobe.

(Z, represents the cap 011 the tuloe.

e, represents the main spring.

f, represents the cocking oatch.

. represents t-he hitching string having a pin h, at its encls.

z, represents the tr1gger stnng, havmg a hook j, at its encls.

7c, represents a small lever used for cooking the machine by inesrting its small end Z, into a hole m, in the encl of the ha1nmer. It is also used for plaoing the cap on the oaptube, the cap being hold by the jaws of the cleft encl n.

Figs. 4 and 5, are illustrative views showing some of the various methods in which the machine may loe applied.

Fig. 4 represents a man aloout being robbed of bis pooket book by the band of a thief, but having taken the preoaution to provide himself with ono of my alar1ns with the hitching string g, seourecl to the pocket book, and the trigger string z, hooked to the sicle of his pockets, or any contiguous part of his olothing, 110 sooner cloes the thief pu1l on the pocket book than the alarm explodes, und t-hus gives prompt notice to the intendecl victim, and to the bystanclers also,of bis intendecl robbery.

Fig. 5, shows the applioation of my maohine, as a burglar ala1m, boing attaoheol to tl1e insicle of the door, of a roorn in Whi0h a traveler is supposed to have retirod for the night. The hitching string is pinned rather slightly by Che pin h, to the casing of the door, while the trigger string is hooked to the cloor itself, taking oa1e to leave the trig ger string one or two inohes slack. N0 sooner cloes an intrucler open the door a little, than the pin h, is pulled out, and the weight of machine causes a strain on tho trigger string, and an explosion im1necliately takes place, alar1ning the inmates of this and probably of the neighboring rooms.

Ingenuity anc1 clue presence of 1nincl and precaution would undoubtedly suggest a great variety of other pa1ticular ciroumstances, in Whi0h the possessor of such an article coulcl apply the Same to the security of bis person ancl property, while t he whole machine for convenience is capalole of being reducecl to a very diminutive bulk, without impairing its effioiency.

In the pocket, thief, and burglar alarm const1uotecl in the for1n and 1nanner representecl and described, I clai1n The combination and arrangement of the inclepenclent lever k, adapted to cap and cool: the alar1n, while both tl1e cap-tube and hannner are arlfanged within and clo not project outside the shell o1 case.

ISAAC GOODSPEED.
